Ups and downs of Miley Cyrus' 'Bangerz' tour – Pop star Miley Cyrus performs in Mexico City during a "Bangerz" tour stop on Friday, September 19. Earlier in the week, Cyrus was criticized for her dance moves during a concert in Monterrey, Mexico. On Mexico's Independence Day, Cyrus' backup dancers used a Mexican flag to spank the oversized fake bum Cyrus was wearing. Mexico's Interior Ministry opened a federal investigation on the matter. Here are a few other issues that have cropped up during Cyrus' tour, which she launched in February.

Ups and downs of Miley Cyrus' 'Bangerz' tour – Tragedy struck in early April with the death of the singer's favorite pooch, Floyd. Cyrus tweeted to her Boston fans in advance of her concert there that she was "beyond miserable." The gift of a new dog from her mother apparently did little to console her, as Cyrus later tweeted that she gave the new dog away to a friend.

The statement sent to CNN by Cyrus' representative did not specifically say it, but it implied that her upcoming shows over the next week -- including Nashville; Louisville, Kentucky; Philadelphia; Uniondale, New York; and Connecticut -- would be off.

"Miley was suffering from a sinus infection during her tour in N.C. a week ago. She was prescribed the antibiotic Cephalexin which she has now suffered an extreme allergic reaction to," the statement said. "This type of extreme reaction can last from five to 27 days in these types of cases.

"She will remain hospitalized and is under a doctor's care until we see some improvement in her condition and is asking for your compassion and privacy at this time. Miley is devastated about missing shows and possibly disappointing her fans."
